On a small SSD VPS I got 2 GB of RAM and 2 vCPU core (dedicated to my server), virtualized via KVM. So far so good. The server is mainly used for databases (MySQL) and fast network file storage (via sshfs). Currently around 5 folders are mounted to a remote server via sshfs.
When I look into htop I can see 100% CPU load even though when sorting processes by CPU usage none of the processes take up that much CPU on it's own or multiple processes combined. Also the load average indicates that the server is mainly dozing around. From this question I found out that the blue CPU bar indicate that a "Low priority thread" takes up the CPU.
Here are some screenshots:
How can I find out which process is using up all CPU power? Is it even using CPU power or is that just a visual bug, caused by KVM? Does sshfs use cpu power that cannot be tracked from userspace?
